What is better use for int input ? 回答1: You still have a newline in the stream after cin>>age; , which is giving you an empty string for the name. You could solve it by just adding another getline() call after getting the age and throwing

I initially used html2canvas and domToImage to take client-side screenshots but it doesn't render the image exactly as it is shown in the web page. Reddit user /pamblam0 suggested I look into Google's Puppeteer. How it works is that it launches a headless chromium browser which goes to my react app on localhost then gets a screenshot of that whole page easily. My problem

Something like Single Consumer - Not Working - Doesn't return offsets for some of the provided topic partitions ( ex. 10 provided - 5 Offsets Returned ) Consumer consumer; static { consumer = createConsumer(); } run() { List<String> groupIds = getConsumerGroups()
